Pre-nuclear potatoes are the earliest generation of potatoes. These are grown from tissue culture in our greenhouses. As these have never been grown in native soil and they are free of disease. These marble sized tubers can produce high yields of up to 200% or more by weight. Old standard since 1932 and very popular in the eastern U.S. Flat to round, white and drought resistant it produces high even yields. Good baked, mashed or as hashbrowns and fries. Stores well and tastes great.
